Learning anything new is all well and good, but the thing that's actually valuable to society and "america's future" isn't really more coders, it's people who are really fantastic at what they do; whatever it may be. I'd rather someone dedicate their life to becoming the best preserve-maker in the world than fixing bugs in groupon. The preserve-maker may not reach billions of people with his/her work, but based on my own observations, I've found that the relative quality of one's achievements in a field has more leverage than the scale.
hmm I suppose it seems obvious to some people, but I've met a number of people trying to become programmers for reasons that won't get them very far. Just my two cents.
